Paid Drupal services

Hello Drupallers!

What's the best development path if I am trying to have a pure e-comm site (ie one with ERP as well as the shopping cart side)?

This will be included in my final RFP package as a specification. I am pretty sure that I would like to run this alongside CiviCRM for the Customer management part. Here's what I need:

1. Inventory control (both shipping and receiving goods) (E-Comm has a rudimentary module for that)
2. Generating and managing purchase orders & invoices
3. Warranty Management
4. Generating reports
5. Export and import from CSV files for mass updates and other reporting as needed.

Here are some possible development paths:
1. Use E-Comm module, and have a ERP module built to work with it.
2. Use E-Comm module, and CCK build fields for the ERP bits required. (Not even sure whether this would work. It would be messy in the end, I think?)
3. Use Ubercart, and have a ERP module built to work with it.
4. Use Ubercart, and CCK build fields for the ERP bits required. (Not even sure whether this would work. It would be messy in the end, I think?)
5. New module build from scratch, designed for B2B, B2C multi-channel distribution model.

I was thinking there was a group for consultants and people looking for such. Anyway, from the 'Drupal showcase':

We have been working with Drupal for a few months now, and this week I thought to rebuild our website with Drupal.

We have a number of web site projects using Drupal currently in the works. Announcing our availability as Drupal consultants in this forum.

Before installing my drupal's site, i want to know what is correct to do to be legal.
If i use drupal 5.2 and theme (jazzlite for exemple), do i have to pay something ?
Drupal offer to hide theme's logo and other things, changing name of the site, etc.

So if my site is visible in the web, what do i have to know? (i know how to use modules amd themes)
i talk just about GPL and licences.

I want to add music, videos and pictures.

Thanks. (excuse my english)

I have a small budget to find someone to help me create a small module using the hook_form_alter that will allow me to pass a variable from a page like this http://www.used-computers-dc.com/fujitsu-e-series-lifebook-p3-850mhz to a Webform page.

Description:

Are you interested in building a kick-ass Drupal-based social networking site? Movieset™ is looking to add another member to its development team! The successful candidate will have a track record of developing and deploying dynamic web sites based on LAMP stack, and working with other team members in a local or distributed environment.

Wondering if anyone could give me a rough estimate of how long it would take to built a poll module where I can choose any number of questions and each question can have any number of multiple choice answers.

I'd also like to display the poll results for the user after they vote. Maybe a percentage bar r something.

Is this a major headache for Drupal 4.7?

Thanks!
